Nina saved money in her piggy bank to buy a music player she started by saving 30$ that she received for her birthday and then she saved 10$ from her allowance each month for 6 months. The table below shows the total amount of money Nina had save at the end of each month for 6 months .

Answer:

No, it does not represent a proportional relationship.

Step-by-step explanation:

The ratios do not reduce to the same value.

40/1 = 40

50/2 = 25

60/3 = 20

We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.
